＝International Space Station
（国際宇宙ステーション）
The International Space Station (ISS) goes around the earth 400 kilometers above us. It takes 90 minutes to fly around the earth. For 45 minutes you see the day view, and then in the next 45 minutes you see the night view. It is very dark at night. The stars are shining, and the Milky Way stretches on and on. Our blue planet Earth looks like an oasis in the vastness of space.
